1. 16. Free Boundary Problems of Obstacle Type, a Numerical and Theoretical Study

   Författare :Mahmoudreza Bazarganzadeh; Henrik Shahgholian; John King; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Partial differential equations; Numerical analysis; Free boundary problems; Mathematics; Matematik;

   Sammanfattning : This thesis consists of five papers and it mainly addresses the theory and schemes to approximate the quadrature domains, QDs. The first deals with the uniqueness and some qualitative properties of the two QDs. The concept of two phase QDs, is more complicated than its one counterpart and consequently introduces significant and interesting open. LÄS MER

3. 17. Problem eller tillgång? En studie om social och etnisk mångfald i högskolan

   Författare :Thérèse Hartman; Christina Gustafsson; Johanna Esseveld; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Higher education; ethnicity; class; democracy; equality; selection; recruitment; redistribution; Education; Pedagogik; pedagogik; Education;

   Sammanfattning : The general problem I am addressing concerns the role of the university as an actor for increased equality and democracy. How does this role manifest itself in selecting and recruiting students to the university and how does it influence teaching? The aim of my empirical study is to describe and understand processes and contexts where ethnicity and class are important. LÄS MER

4. 18. Two Problems in non-linear PDE’s with Phase Transitions

   Författare :Karl Jonsson; Henrik Shahgholian; Tomas Sjödin; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conductivity jump; Free boundary problem; Quasilinear elliptic equation; Mathematical techniques; Nonlinear analysis; Free boundary; Free-boundary problems; Quasi-linear elliptic; Quasilinear elliptic equations; Hele-Shaw flow; non-local; implicit function theorem; Heterogeneous Multi Scale; HMM; Finite Element; FEM; FE; Mathematics; Matematik;

   Sammanfattning : This thesis is in the field of non-linear partial differential equations (PDE), focusing on problems which show some type of phase-transition. A single phase Hele-Shaw flow models a Newtoninan fluid which is being injected in the space between two narrowly separated parallel planes. LÄS MER

5. 19. Toward Dependable Multiple Path Planning for Autonomous Robots with Obstacle Avoidance and Congestion Control

   Författare :Lan Anh Trinh; Mikael Ekström; Baran Curuklu; Lucia Pallottino; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

   Sammanfattning : Over decades, automatic robots that are pre-programmed to perform repetitive tasks in industrial production has been reaching the cutting edge of technology. There is emerging the next development with autonomous control, where a robot is able to have some levels of its own decision, i.e. self-governing, without direct controls from humans. LÄS MER

7. 20. Reasons for All Seasons : An Outline of Rationalist View of Moral Concepts

   Författare :Tomasz Pol; Ingmar Persson; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Philosophy; moral concepts; the Reconciliation Problem; ethical rationalism; rational requirements; reflective agency; the Aristokantian proposal; generic deontic rules; Filosofi; Philosophy subjects; Filosofiämnen; Practical Philosophy; praktisk filosofi;

   Sammanfattning : The aim of this thesis is to provide an adequate view of moral concepts. The major obstacle that stands in the way of providing such a view is the problem of combining two general features of moral judgments that seem to be constitutive of their meaning, namely objectivity and practical significance.
